In addition to the above section, features can also be checked for disabled/enabled status by the following: | |||
<table width="100%" border="1"> | |||
<tr> | |||
<th>Feature</th> | |||
<th>Enabled</th> | |||
<th>Disabled</th> | |||
</tr> | |||
<tr> | |||
<td>Direct2D (Windows)</td> | |||
<td>about:support will show "Direct2D Enabled: true"</td> | |||
<td>about:support will show "Direct2D Enabled: false"</td> | |||
</tr> | |||
<tr> | |||
<td>Direct3D 9 Layers (Windows)</td> | |||
<td>about:support will show "GPU Accelerated Windows: 2/2 Direct3D 9" *if it says Direct3D 10, this is not possible to test on this setup</td> | |||
<td>about:support will show "GPU Accelerated Windows: 0/2" and will not list the rendering API</td> | |||

<td>about:support will show "WebGL Renderer: <some error>" which contains some information about why the renderer is blocked</td> | |||

<tr> | |||
<td>WebGL, ANGLE Variant (Windows)</td> | |||
<td>about:support will show "WebGL Renderer: ANGLE( <your render> )" and will not contain anything about being blocked for a driver version or similar messages. *NOTE: DO NOT assume that if it says "OpenGL ES 2.0" or some such that it is using OpenGL; the only important thing is that it says "ANGLE"</td> | |||

<td>WebGL MSAA</td> | |||
<td>Go to https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/demos/mozilla/spore/index.html and compare the model to [[media:msaa_comparison.png|this reference]]; if it looks like the left image, MSAA is enabled.</td> | |||
<td>Go to https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/demos/mozilla/spore/index.html and compare the model to [[media:msaa_comparison.png|this reference]]; if it looks like the right image, MSAA is disabled. *NOTE: this is not a scientific test. MSAA may be disabled but you cannot be certain that it's blocked. the card could simply not support it. the best way to be sure is to download a utility that checks your GPU's available extensions and if antialiasing is not in that list, it is simply not supported</td> | |||
